中文摘要：
断裂特征、典型油藏解剖和剩余压力分布特征研究结果表明，鄂尔多斯盆地西缘麻黄山地区中生界油气分布和成藏组合在不同构造带有较大的差别，油藏受构造影响明显。西缘冲断带主要发育源外成藏组合和远源成藏组合，油藏主要为断块油藏和断背（鼻）油藏，油藏面积小、油柱高度大、储量小、产量高；中央凹陷带主要发育源内成藏组合，主要为致密低渗岩性油藏，油藏面积大、油柱高度小、产量低；而东部凸起带，源内、源外和远源成藏组合均发育，油藏则主要为背斜-岩性油藏。
英文摘要：
An analysis is performed on the fault characteristics, typical reservoirs, and residual pressure distribu- tion in the Mesozoic of the Mahuangshan area in the western margin of Ordos Basin. The results show that the hydrocarbon distribution and plays there vary greatly in different structural belts and structural control on reservoirs is significant. In the thrust belt in the western margin, proximal plays and distal plays are predominant. The reservoir types here are mainly fault-block and faulted anticlinal （nose） reservoirs,featuring in small area but high oil column and small reserve but high production. While in the central depression, the indigenous plays are predominant. The reservoirs here are tight low-permeability type featuring in large area, low oil column, and low production. In the eastern uplift belt, proximal, distal and indigenous plays all occur. The reservoirs are dominated by anticline-lithologic reservoirs.
